Imagine a Melbourne homeowner planning to rent out a new backyard granny flat. The design looks comfortable, the entry path is private and the weekly rent estimate feels promising.
Then one question changes the calculation: should the rent include bills?
Many renters search for simple, predictable arrangements. Your keyword table shows strong search interest around phrases like "cheap granny flat for rent including bills". That tells us renters care about total weekly cost, not just the rent line.
For owners, though, including bills is not automatically better. It can improve appeal, but it can also affect net return.
Why renters like bills included
Bills included can make a granny flat feel easier to compare. A tenant may prefer knowing the likely weekly cost upfront, especially if the space is compact and self-contained.
This can be useful when marketing to singles, couples, students or people who want a simple rental setup.
But from the owner side, the question is not only, "Will it attract enquiries?" It is, "Will the rent still cover the real costs?"
What costs need to be counted?
Before setting a rent that includes bills, owners should think about:
- electricity use
- water use
- hot water
- internet, if included
- heating and cooling
- maintenance
- vacancy allowance
- property management, if using an agent
If these are not measured or estimated carefully, gross rent can look stronger than the real return.
For a broader rental planning view, start with the Rental Income Guide.
Separate metering can change the decision
The right approach may depend on how services are set up.
If the granny flat has separate metering or a clear usage arrangement, rent can be easier to structure. If services are shared with the main house, the owner needs to be more careful about how costs are estimated and explained.
Service setup can also affect the build budget. Our Granny Flat Cost Victoria guide explains why connections and site-specific items should be reviewed early.
Higher rent is not the same as higher ROI
Including bills may allow a higher advertised rent, but that does not mean the return is better.
For example, if the weekly rent is higher but the owner absorbs uncertain utility usage, the net income may be less predictable. A cheaper-looking rent without bills may attract a different tenant group, but it may leave the owner with cleaner cost control.
This is why ROI should be tested using net income, not only advertised rent. You can use the ROI Calculator to compare both scenarios.
Land and design still matter
Bills are only one part of the rental decision. A granny flat with a private entry, good natural light, practical parking and a comfortable layout may rent more easily than one that feels squeezed into the backyard.
Before choosing a rent strategy, make sure the block can support a layout that tenants will actually want. The Land Eligibility Check can help identify access, privacy and service issues early.
A practical owner-first approach
If you are considering bills included, compare three numbers:
- rent without bills
- rent with a conservative allowance for bills
- net income after vacancy and expenses
The best option is the one that stays attractive to tenants while still producing a realistic return.
